Koden expanded its lineup of professional grade digital echosounders for 2013 with the addition of its new CVS-1410B and CVS-128B Broadband Sounders — powerful and versatile machines designed to meet the demands of commercial fishing boats and high-end sportfishing yachts.
Kodenʼs CVS-1410B is a powerful 1kW RMS sounder with a 10.4” vertically oriented TFT color LCD display for superior target resolution and presentation. The CVS-128B boasts a powerful 1kW RMS transmitter and a high-definition 8.5” vertical TFT color LCD display. The key to both these soundersʼ superior performance under a wide range of conditions is Koden Digital Filtering (KDF) technology, together with Kodenʼs broadband Flex-Frequency capability. Flex-Frequency allows fishermen to adjust both high- and low-frequency settings within the given range, improving the strength and clarity of returns in any situation while eliminating interference from nearby fishing vessels.
This is achieved by pairing the CVS-1410B or CVS-128B with the latest Broadband/CHIRP Transducer technology from Airmar. Depending on the specific transducer selected, operators of these sounders can select any frequency in 0.1kHz steps between 38kHz - 75kHz (Low/Medium Range Transducer); or 42kHz - 65kHz and 130kHz – 210kHz (Low/High Range Transducer). This nearly limitless ability to fine tune operating frequencies ensures optimum target detection, resolution and display clarity in every situation.
Both the CVS-1410B and CVS-128B are packed with many other professional features, including Detection Area Display that shows fishermen the exact bottom area covered by low- and high-frequency beams. This information is helpful in targeting fish either under the vessel or off to the side. Koden Sona-Tone alerts the operator using different sounds when fish targets or schools of fish are detected. These sounders also store up to 10 screen images in a built-in memory and make them available for review with the touch of a button. This is a useful reference tool for captains revisiting previously productive spots.
The 2kW CVS-1410B has an operating range of 10 to 6,000 feet, while the 1kW CVS-128B has a maximum range of 3,600 feet. Both provide a wide range of presentation modes, including High/Low Frequency, A-Scope, Bottom Lock, Bottom Discrimination, Bottom Zoom, Bottom Follow Zoom, Nav Mode, Vertical Split and Horizontal Split. Background palettes include Marine Blue, Blue, Black, White, Nighttime and five other colors for optimum viewability in all light conditions. Users can also select an operating language from among English, Chinese, French, Greek, Italian, Japanese, Korean, Spanish and Thai.
